A student needs exactly 1 gram of baking powder to conduct an experiment. The balance reads 0.37 grams. How much more baking powder does the student need?

A. 50 grams
B. 63 grams
C. 75 grams
D. 36 grams

B

Explanation:

If the student needs one gram but so far only has 0.37 grams, then the amount they need is the difference between what they need and how much they already have. 1-0.37=0.63 grams.

...which isn't actually an option because none of them have decimal points but I would say it is B anyway because it is the equivalent ratio and maybe there was a typo.

Hope this helped!

the temperature of the gas, in k, not celsius.
