Sea water contains 53 PPM of Na2CO3 find mass of and a Na2 CO3. present in a glass of water.

We first need to know the volume of the glass of water in order to find the mass of Na2CO3 present. Let's assume a typical glass of water has a volume of 250 mL (or 0.25 L).

To find the mass of Na2CO3 present, we need to use the given concentration (53 PPM) and convert it to a mass/volume concentration:

53 PPM = 53 mg/L

Now we can use this concentration to find the mass of Na2CO3 in the glass of water:

mass = concentration x volume
mass = 53 mg/L x 0.25 L
mass = 13.25 mg

Therefore, there are 13.25 mg of Na2CO3 present in a typical glass of water.
