A substance’s molar mass tells you the mass of one mole of that substance. In your case, nitrogen dioxide, NO2 , is said to have a molar mass of **46.01 g**/mol . That means that every mole of nitrogen dioxide will have a mass of 46.01 g .

n(NO2) = **1.89 moles**.

The answer is **46.0055**.

Thus **2.49837 moles** of $N{{O}_{2}}$ are present in 114.95 g.

Hence, number of molecules in 1.5 moles of ammonia is **9.033 × 1023**.

According to the above equation, **3 moles** of NO2 react with one moles form 2 moles of HNO3.

NO2=32×7.33=**10.995 moles**.

**Divide the number of grams of the compound**, NaOH, by the molecular weight and as a result, the grams (g) unit cancels and all we have left is the unit mol (moles).

Therefore, there are **1031.85 grams** in 4.50 moles of Ba(NO2)2 .

There are **3.54 moles** of N in nitrous oxide. The first step in solving this problem is to convert 78.0 grams of nitrous oxide to moles.

=**1.93⋅mol** .

A normal mole is usually **an evenly colored brown, tan, or black spot on the skin**. It can be either flat or raised. It can be round or oval. Moles are generally less than 6 millimeters (about ¼ inch) across (about the width of a pencil eraser).

That means that a mole of N2 has a mass of **28 grams**.

What is the mass of this quantity of ammonia, and in terms of moles, how many atoms we got here? So first we calculate no of molecules in 2 moles of NH_3 . So we have 2×6.022×10 molecules of = **12.044×10 molecules**. Thanks!!!

1mol of nitrogen has a mass of 28.02g, while 3mol of hydrogen has a mass of 6.06g, and 2mol of ammonia has a mass of **34.08g**.

Well, if there are 6.022×1023 Ba(NO2)2 formula units there are **229.34⋅**g by definition.

432/261.344 = **1.653**. Since the answer should have 3 significant figures, the answer should be 1.65 moles.

The answer is **1173.327**. We assume you are converting between grams Ba(No2)2 and mole. You can view more details on each measurement unit: molecular weight of Ba(No2)2 or mol The SI base unit for amount of substance is the mole.

Each mole of nitrous oxide, N2O N 2 O , contains **1 mole of nitrogen** atoms. The quantity of moles n of nitrous oxide can be calculated from its mass m by dividing the latter by the molar mass MW of nitrous oxide, which is 44.01 g/mol.

Hence, **2.94 mol** nitrogen is present in 65 grams of nitrous oxide.

How many moles of nitrogen are in 87.0g of nitrous oxide? – Quora. Number of moles of Nitrous oxide in 87g=87/44= **1.977 moles**. One mole of N2O contains= 1- mole of Nitrogen.

To calculate the molar mass of a compound, calculate the molar mass of each element in the compound, **then multiply the element’s atomic mass by the number of atoms of that element in the compound**. Add the molar masses of each element in the compound to calculate the molar mass of the compound!

A mole is defined as **6.02214076 × 1023 of some chemical unit**, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
