Question

0.4 part of a 9.3 g ornamental chain is made of gold. If the chain is cut into 6 equal pieces, how much gold is there in each piece?

A. 0.6 g
B. 1.2 g
C. 1.5 g
D. 2.0 g

Answer 1

To find out how much gold is there in each piece, we need to calculate the mass of gold in the chain and divide it by the number of pieces.

Step-by-step explanation:

To find out how much gold is there in each piece, we need to calculate the mass of gold in the chain and divide it by the number of pieces. First, we find the mass of gold in the chain by multiplying the total mass of the chain (9.3 g) by the fraction of gold in the chain (0.4). This gives us 0.4 x 9.3 = 3.72 g of gold.

To find the mass of gold in each piece, we divide the mass of gold in the chain (3.72 g) by the number of pieces (6). This gives us 3.72 g / 6 = 0.62 g.

Therefore, there is approximately 0.62 g of gold in each piece.
