The mass of 1 cm³ of zinc is 7.1 g. Calculate the mass of a zinc part with a volume of 4.3 cm³.

The mass of 1 cm³ of zinc is 7.1 g.

Let’s calculate the mass of a zinc part with a volume of 4.3 cm³.

Let x be the mass of a part with a volume of 4.3 cm³.

Let’s write the expression in the form:

1 cm³ – 7.1 grams;

4.3 cm³ – x grams;

We multiply the values of the expression cross by cross and get a linear equation in the form:

1 * x = 4.3 * 7.1;

x = 4.3 * 7.1;

x = 30.53.

This means that the mass of a part with a volume of 4.3 cm³ is equal to 30.53 grams.

Answer: 30.53 grams.
