What is the mass of 040 mol of aspirin, C_(9)H_(8)O_(4) 45 g 80g 72g 160g 10.8 g

To find the mass of 0.40 mol of aspirin (C9H8O4), we need to calculate the molar mass of aspirin first.<br /><br />The molar mass of aspirin is calculated by adding the molar masses of each element in the compound:<br /><br />Molar mass of C = 12.01 g/mol<br />Molar mass of H = 1.01 g/mol<br />Molar mass of O = 16.00 g/mol<br /><br />Molar mass of C9H8O4 = (9 * 12.01) + (8 * 1.01) + (4 * 16.00) = 180.16 g/mol<br /><br />Now, we can calculate the mass of 0.40 mol of aspirin:<br /><br />Mass = Molar mass * Number of moles<br />Mass = 180.16 g/mol * 0.40 mol<br />Mass = 72.064 g<br /><br />Therefore, the mass of 0.40 mol of aspirin is approximately 72 g.
