Answer:
The ratio of the mass of an adult rhino to the mass of a small egret is
(1400 kg)/(0.76 kg) = 1842.11
The ratio of the mass of a proton to the mass of an electron is
1836.15
The two ratios are very similar, the ratio of the masses of the proton to the electron being slightly smaller.
Answer:
3.88%
Explanation:
Given parameters:
Grams of solute = 3.55g of NaCl
Grams of solution = 91.55g of solution
Mass percentage
of NaCl(%) = grams of solute/grams of solution x 100
Mass percent = 3.55/91.55 x 100
Mass percent = 3.88%
