To determine the number of grams in 1.40 moles of dinitrogen oxide, we need to use the molar mass of dinitrogen oxide, which is given by the sum of the atomic masses of each element in one molecule of dinitrogen oxide.
The atomic masses of nitrogen (N) and oxygen (O) are approximately 14.01 g/mol and 16.00 g/mol, respectively.
Therefore, the molar mass of dinitrogen oxide (N2O) is:
(2 × 14.01 g/mol) + 16.00 g/mol = 44.02 g/mol.
To find the number of grams in 1.40 moles of dinitrogen oxide, we can use the following conversion factor:
1.40 moles of N2O × (44.02 g/mol of N2O) = 61.63 g.
Therefore, there are 61.63 grams in 1.40 moles of dinitrogen oxide.
