(4.99 g) / (3.65 g/mL) = 1.37 mL
The answer to your question is 1.37ml.
Answer:
Saturated Fats
Explanation:
Saturated fats are all of the above.
Also, Saturated fat is very unhealthy. Only consume it in small amounts.
The answer is 267.93 g
Molar mass of CaBr2 is the sum of atomic masses of Ca and Br:
Mr(CaBr2) = Ar(Ca) + 2Ar(Br)
Ar(Ca) = 40 g/mol
Ar(Br) = 79.9 g/mol
Mr(CaBr2) = 40 + 2 * 79.9 = 199.8 g/mol
The percentage of Br in CaBr2 is:
2Ar(Br) / Mr(CaBr2) * 100 = 2 * 79.9 / 199.8 * 100 = 79.98%
Now make a proportion:
x g in 79.98%
335 g in 100%
x : 79.98% = 335 g : 100%
x = 79.98% * 335 g : 100%
x = 267.93 g
n = m/M = 2/18 = 1/9 ~0,1 mol
