Answer:
The answer to the question is 148.3 g
Explanation:
To find moles, you want to get rid of the grams by finding molar mass. Then, you have to get rid of grams using cross multiplication. This is why 148.3 grams is on the bottom; it will get rid of the grams on the original amount leaving you moles.
AgNO3(aq) + NaCl(aq) = AgCl(s) + NaNO3
MWt AgNO3 = 169.87; AgCl = 143.32
From the eqn 169.87 g of AgNO3 yield 143.32 g of AgCl
1.000g of AgNO3 yield 143.32/169.87 g of AgCl
Hence 4.27 g will yield (143.32/169.87)×4.27 g of AgCl
= 3.60 g of AgCl which is the theoretical yield.
% yield = (2.56/3.60)× 100 = 71.1%
A skilled chemist (e.g., Marie Curie) would get close to 100%.

Answer: it’s a I believe
Explanation: protons are smaller then atoms which means they have less mass
