Please help :) A chocolate chip cookie recipe calls for 0.050 moles of baking soda (NaHCO3). How many grams should the chef mass out?

Answer=I have no idea

4.2 g

Explanation:

Note that the number of moles is equal to the actual given mass of the substance over its molar mass.

n = m/M, where n is the moles, m is the given mass, M is the molar mass.

In manipulating this formula, you get that the given mass is equal to the number of moles multiplied by the molar mass of substance.

m = n x M.

(Na = 23, H = 1, C = 12, O = 16)

Molar mass = 23 + 1 + 12 + (16x3)

= 84

1) m = 0.050 x 84
2) m = 4.2 g

Hope this helps, brainliest would be appreciated :)

The answer is b because c don't explain why the moths are on them and it isn't a because as we know only one species of moth does this
