Convert 25 mL of 0.80 mol/L Mg(NO3)2(aq) into moles
moles of Mg(NO3)2 = 0.8 x (25/1000) = 0.02
yes but I put the answer 0.02 moles
Is this a question?
To convert 25 mL of 0.80 mol/L Mg(NO3)2(aq) into moles, you can use the formula:
moles = concentration (molarity) x volume (in liters)
Given:
Concentration = 0.80 mol/L
Volume = 25 mL
First, convert the volume from milliliters to liters by dividing by 1000:
Volume = 25 mL ÷ 1000 = 0.025 L
Now, use the formula to calculate the number of moles:
moles = 0.80 mol/L x 0.025 L = 0.02 moles
Therefore, 25 mL of 0.80 mol/L Mg(NO3)2(aq) is equal to 0.02 moles.
To convert 25 mL of 0.80 mol/L Mg(NO3)2(aq) into moles, you can use the formula:
moles = concentration x volume
First, convert the volume of 25 mL to liters by dividing it by 1000:
25 mL ÷ 1000 = 0.025 L
Next, multiply the concentration of 0.80 mol/L by the volume of 0.025 L:
0.80 mol/L x 0.025 L = 0.02 moles
Therefore, 25 mL of 0.80 mol/L Mg(NO3)2(aq) is equal to 0.02 moles.
