To find the number of grams in 4 moles of sodium nitrate (NaNO3), you can use the molar mass of NaNO3.
The molar mass of NaNO3 is calculated as follows:
- Sodium (Na) has a molar mass of approximately 22.99 g/mol.
- Nitrogen (N) has a molar mass of approximately 14.01 g/mol.
- Oxygen (O) has a molar mass of approximately 16.00 g/mol.
So, the molar mass of NaNO3 is:
22.99 (Na) + 14.01 (N) + (3 * 16.00) (3 oxygen atoms) = 85.00 g/mol
Now, to find the grams in 4 moles, you can use the following calculation:
4 moles * 85.00 g/mol = 340 grams
So, there are 340 grams of sodium nitrate (NaNO3) in 4 moles.
