What is the density of this gas at STP? type your answer. g/1.(3 decimal places)

a. To find the number of atoms in the sample, we can use Avogadro's number, which is 6.022 x 10^23 atoms/mol. <br /><br />Number of atoms = (1.50 mol) x (6.022 x 10^23 atoms/mol) = 9.03 x 10^23 atoms<br /><br />b. To find the mass of the sample, we need to know the molar mass of the gas. Since the type of gas is not specified, we'll assume it's a common gas like helium (He) with a molar mass of 4.00 g/mol.<br /><br />Mass = (1.50 mol) x (4.00 g/mol) = 6.00 g<br /><br />c. To find the volume of the sample at STP (Standard Temperature and Pressure), we can use the ideal gas law: PV = nRT. At STP, the temperature is 0°C (273.15 K) and the pressure is 1 atm.<br /><br />Volume = (1.50 mol) x (22.4 L/mol) = 33.6 L<br /><br />d. To find the density of the gas at STP, we can use the formula: Density = Mass/Volume.<br /><br />Density = (6.00 g) / (33.6 L) = 0.179 g/L
