Final answer:
0.4 part of the 9.3g chain is made of gold, which equals 3.72g. Dividing this by 6, we find that each piece of the chain contains 0.62g of gold.
Step-by-step explanation:
To determine how much gold is in each piece of the chain when it is cut into 6 pieces, we first need to calculate the total amount of gold in the entire chain. We do this by multiplying the total mass of the chain by the gold proportion.
Total gold in the chain = 0.4 × 9.3g = 3.72g
Next, since the chain is divided into 6 pieces, we divide the total amount of gold by the number of pieces.
Gold in each piece = 3.72g ÷ 6 = 0.62g
Therefore, option C. 0.62g is the correct amount of gold in each of the 6 pieces.
