How many moles of CaCl2 have you delivered to the flask if you add 20.53 mL of 0.511 M CaCl2 from the buret? (Just enter the number not the units. Sig figs are graded.)
A the CaCl2 solution is 0.511 M, it mean that there are 0.511 moles of CaCl2 are present in 1000 mL. Therefore, we can consider that 0.511 moles of CaCl2 is equals to 1000 mL
1000 mL = 0.511 moles of CaCl2
For 20.53 mL,
20.53 mL = (20.53 x 0.511) / 1000
= 0.0104
Therefore, 0.0104 moles of CaCl2 have been delivered to the flask
