a sample has a density of 55g/mol and a volume of 11mL the sample mass is?
55 g/mol x 1 mol/22.4 L x 0.011L = __ g
To find the mass of the sample, you can use the formula:
mass = density × volume
Given that the density is 55 g/mol and the volume is 11 mL, you can substitute these values into the formula to calculate the mass:
mass = 55 g/mol × 11 mL
Before we proceed with the calculation, we need to account for the unit conversion. The volume is given in milliliters (mL), but the density is given in grams per mole (g/mol). We need to ensure that the units are consistent before calculating the mass.
Since 1 mL is equal to 1 cm³, we can convert the volume from milliliters to cubic centimeters (cm³):
11 mL = 11 cm³
Now, the units are consistent. We can proceed with the calculation:
mass = 55 g/mol × 11 cm³
Next, we notice that the unit of cubic centimeters (cm³) is equivalent to grams (g) for density. So, the mass is equal to the volume:
mass = 11 g
Therefore, the mass of the sample is 11 grams.
