What mass of sugar exists in a #754.83*mL# volume of #12.38%(m/v)# of glucose?

Answer 1

Wyatt Adkins

Approx. #100*g# of glucose are present............and I wondered how they measured that volume.

If #"mass"/"volume"=12.38%#, then a volume of #754.83*mL# contains a MASS of #93.45*g# #"glucose"#.

What is the concentration of glucose in #mol*L^-1#?

To calculate the mass of sugar, use the formula: mass = volume × concentration. Substitute the values: mass = 754.83 mL × 12.38 g/L. Convert the concentration to g/mL if necessary. Calculate the result.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
