a pharmacy stocks NaCI 0.9 in 500ml bags how much NaCL is in one 500ml bag. I get the answer but need help with problem
The concentration of NaCl in the 500ml bag is 0.9%, which means that in 100ml of the solution, there is 0.9g of NaCl.
To find out how much NaCl is in the 500ml bag, you can use the formula:
Amount of NaCl (g) = concentration of NaCl (%) x volume of solution (ml) / 100
Applying this formula, we get:
Amount of NaCl (g) = 0.9 x 500 / 100 = 4.5
So, there is 4.5g of NaCl in one 500ml bag.
