Question

How many miles of beryllium chloride BeCl2 are needed to make 130 ml of a 0.025 M solution

Answer 1

= 0.00325 moles of beryllium

Step-by-step explanation:

Molarity or concentration is given by the formula;

Molarity = Number of moles/Volume in L

Therefore, to get the number of moles

Moles = Molarity × Volume

= 0.025 M × 0.13 L

= 0.00325 moles of beryllium
