Question

Chemistry: if i have an unknown quantity of a gas at a pressure of 0.5 atm, a volume of 25 liters, and a temperature of 300k, how many moles of gas do i have

morris9878 · Accepted Answer

5.22*1022 molecules of glucose (C6H12O6) is equal to 15.08 grams

Explanation:

Number of molecule of glucose in one mole $= 6.023 * 10^{23}$

Now mass of one mole of glucose = 180 grams

Number of moles in $6.023 * 10^{23}$ molecules of glucose = 1

Number of moles in molecules of glucose = $\frac{1}{6.023 * 10^{23}}$

Number of moles in $5.22 * 10^{22}$ molecules of glucose = $\frac{5.22* 10^{22}}{6.023 * 10^{23}}$ = 0.083 moles

Weight of 0.083 moles

$= 0.083 * 180\\= 15.08$ grams
