Question

A student takes a measured volume of 3.00 M HCl to prepare a 50.0 mL sample of 1.80 M HCl. What volume of 3.00 M HCl did the student use to make the sample? Use M subscript i V subscript i equals M subscript f V subscript f.. 3.70 mL 16.7 mL 30.0 mL 83.3 mL

Answer 1

Answer:

it is 30.0 on edge

Explanation:

i got 100% on the test

Answer 2

The volume of 3.00 M HCl that the student use to make the sample is 30mL.

How to calculate volume?

The volume of a solution can be calculated by using the following expression:

C1V1 = C2V2

Where;

• C1 = initial concentration
• C2 = final concentration
• V1 = initial volume
• V2 = final volume

3 × V1 = 50 × 1.8

3V1 = 90

V1 = 30mL

Therefore, the volume of 3.00 M HCl that the student use to make the sample is 30mL.
