Question

calculate the mass of dinitrogen tetroxide n2o4 that contains a trillion ×1.001012 nitrogen atoms. be sure your answer has a unit symbol if necessary, and round it to 3 significant digits.

Answer 1

The mass of dinitrogen tetroxide the number of Nitrogen atoms are 46 x 10^9 gram

Given:

number of nitrogen atoms = 1 x 10^12 atoms

To Find:

mass of dinitrogen tetroxide

Solution:

From the molecular formula of dinitrogen tetraoxide;

molar mass of dinitrogen tetraoxide = 92 g/mol

92 g of dinitrogen tetraoxide contains 2 atoms of nitrogen

x g of dinitrogen tetraoxide will contain 1 * 10^12 atoms of nitrogen

x = 92*1* 10^ 9/2

x = 46 x 10^9 gram

Hence, the number of Nitrogen atoms are

Hence, the number of Nitrogen atoms are 46 x 10^9 gram
