How many moles of NaCl are in 2.00mL of 1.00M NaCl?
mols = M x L
Quantitatively
molarity=moles/dm^3
but 1dm^3=1000ml thus
1mol=>1000ml
?mol=>2ml
by crossmultiplication we got 0.002mol
It looks easier to me to 1.00M x 0.002 L = ? mols.
To find the number of moles of NaCl in a given volume and concentration, you can use the formula:
moles = volume (in liters) x concentration (in moles per liter)
First, convert the volume from milliliters to liters:
2.00 mL = 2.00 x 10^(-3) L (since there are 1000 milliliters in a liter)
Next, use the given concentration:
1.00 M NaCl
Now, calculate the number of moles using the formula:
moles = 2.00 x 10^(-3) L x 1.00 M
moles = 2.00 x 10^(-3) moles
Therefore, there are 2.00 x 10^(-3) moles of NaCl in 2.00 mL of 1.00 M NaCl.
