Question

Saline solution used in hospital contains 0.9% sodium chloride
by mass. Calculate the number of grams of sodium chloride
in 0.5 gal of saline solution if the solution has a density of
1.01 g/mL.

Accepted Answer

you have the dead sea With the salinity of around 34%. We're gonna assume the salinity is pretending to sodium chloride present by mass. And I asked calculate the grams of sodium chloride in 30 gallons of seawater, sending a density of 1.24 g per milliliter. We know that the mass percent is the mass of an element divided by the mass of the compound Times 100%. We need to first convert from gallons of seawater two g of seawater. You have 30 gallons And in one gallon You have 3. L. And in one leader live 1000 male leaders. Then we have our density, which is 1.24 grams. Her one male leader. We're gonna get 140,000 188 grams of seawater. So now we need to find the mass of sodium chloride in seawater. Using a mass percent equation, we're gonna have the mass percent sodium chloride equal to the mass of sodium chloride about by the mass of seawater Times 100%. We have 34 percent. He goes, X 140988 grams Times 100%. We're gonna have Times 140988g because X Times 100%. And we can divide both sides by 100%. Please give us x. It was 47,000 935 .92g. It's going to be 4.79 Times 10 to the four grams. Thanks for watching my video, and I hope it was helpful.
