## How do you find the equivalent mass?

The equivalent masses of acids, bases, and salts are calculated as follows: Equivalent mass of an acid = molecular mass of the acid/basicity. Equivalent mass of a base = molecular mass of the base/acidity. Equivalent mass of a salt = molecular mass of the salt/total positive valency of metal atoms.

## What is the equivalent mass of na2co3?

106 g/moleAnswer: 53 g/eq The salt Na2CO3 ionizes to produce 2Na+ and CO3-2. So the charge on both ions is 2. Therefore, the molar mass of Na2CO3 is 106 g/mole.

## What is an example of an equivalent expression?

Examples of Equivalent Expressions 3(x + 2) and 3x + 6 are equivalent expressions because the value of both the expressions remains the same for any value of x. 3x + 6 = 3 × 4 + 6 = 18. and can also be written as 6(x2 + 2y + 1) = 6×2 + 12y + 6. In this lesson, we learn to identify equivalent expressions.
