Answer : The mass of 5.0 moles of ribose is 750 grams.
Explanation : Given,
Moles of ribose = 5.0 moles
Molar mass of ribose = 150 g/mole
Formula used :
[tex]\text{Mass of ribose}=\text{Moles of ribose}\times \text{Molar mass of ribose}[/tex]
Now put all the given values in this formula, we get:
[tex]\text{Mass of ribose}=5.0mole\times 150g/mole=750g[/tex]
Therefore, the mass of 5.0 moles of ribose is 750 grams.
