How many moles of H3PO4 are there in 35.0 mL of 0.60 M H3PO4 solution?
moles = M x L
21
To calculate the number of moles of H3PO4, we need to use the formula:
moles = (concentration × volume) / 1000
In this case, the concentration is given as 0.60 M, and the volume is 35.0 mL. However, we need to convert the volume from milliliters to liters by dividing it by 1000:
Volume = 35.0 mL / 1000 = 0.035 L
Now, we can substitute these values into the formula:
moles = (0.60 M × 0.035 L) / 1000
moles = 0.021 moles
Therefore, there are 0.021 moles of H3PO4 in 35.0 mL of 0.60 M H3PO4 solution.
