Above is a list of density values for various substances. Sara went panning for gold and found a sample that looks suprisingly like gold. She weighed her sample and found the mass to be 20g. She used a graduated cylinder to measure the volume and found it to be 1.036 ml. Is her sample actually gold?

• No, it is actually lead that she found.

• No, she more than likely found pyrite, otherwise known as fools gold.

• Yes, she did find gold.

• There is not enough information to determine what substance she found.
