calculate the moles of solute present in 1.25 centimeter cube of 0.5 M h3po4 solution
Kuttttay ghalat hai tera answerr!!
wrong answer
Dear hifsa
still remember there is a formula
Molarity= mol/dm cube
so ........
0.5= mole/ (1.25/1000)
number of mole= 6.25x10^-4
To calculate the moles of solute present in a solution, you need to use the formula:
Moles = Molarity * Volume
Here's how you can calculate the moles of solute present in a 1.25 cm^3 (cubic centimeter) of a 0.5 M (molar) H3PO4 solution:
Step 1: Convert the volume from cm^3 to liters.
1 cm^3 = 1 mL
1 L = 1000 mL
Therefore, 1.25 cm^3 = 1.25 mL
1.25 mL / 1000 = 0.00125 L
Step 2: Calculate the moles of solute using the formula.
Moles = Molarity * Volume
Moles = 0.5 M * 0.00125 L
Step 3: Calculate the result.
Moles = 0.000625 moles
Therefore, there are 0.000625 moles of solute (H3PO4) present in a 1.25 cm^3 (cubic centimeter) of a 0.5 M (molar) H3PO4 solution.
