01

Part (a) step 1: Given Information

We need to find the final volume when 10%(m/v)HClsolution to give a 2.50%(m/v)HClsolution.

02

Part (a) step 2: Simplify

Now,

Using the formula below, calculate the final volume of 25.0mLof10.0%(m/v)HClsolution diluted to 2.50%HClsolution:

C1V1=C2V2V2=C1V1C2V2=10.0%(m/vHClsolution)(25.0mL)2.50%(m/v)HClsolutionV2=100mL

03

Part (b) step 1: Given Information

We need to find the final volume when 5.00MHCl solution to give a1.00MHClsolution.

04

Part (b) step 2: Simplify

Now,

Using the formula below, calculate the final volume of 25.0mLof5.00MHClsolution diluted to 1.00MHClsolution:

role="math" localid="1653294053632" C1V1=C2V2V2=C1V1C2V2=(5.0MHClsolution)(25.0mL)1.00MHClsolutionV2=125mL

05

Part (c) step 1: Given Information

We need to find the final volume when 6.00MHClsolution to give a 0.500MHClsolution.

06

Part (c) step 2: Simplify

Now,

Using the formula below, calculate the final volume of 25.0mLof6.00MHClsolution diluted to 0.500MHClthe solution:

C1V1=C2V2V2=C1V1C2V2=(6.0MHClsolution)(25.0mL)0.500MHClsolutionV2=300mL
