Answer:
921 g
Explanation:
If S is the mass of silver and G is the mass of gold, then the total mass is:
S + G = 1050
And the total volume is:
S/10.5 + G/19.3 = 60
Using substitution:
S = 1050 − G
(1050 − G)/10.5 + G/19.3 = 60
(1050 − G) (19.3) + G (10.5) = 60 (19.3) (10.5)
20265 − 19.3G + 10.5G = 12159
8106 = 8.8G
G = 921.1
Rounded to 3 significant figures, the mass of the gold is 921 grams.
