ok, so i have to find the mass of the HNO3 in 1 L and the mass of the H2O in 1 L.
I'm given:
HNO3 solution
1.42 g/mL
16M
I'm really terrible at this stuff and it should be easy, but I have no idea where to start.
To find the mass of a substance, you need to multiply its density by its volume. In this case, you want to find the mass of HNO3 and H2O separately in a 1L solution.
Let's start with the HNO3:
Step 1: Calculate the mass of HNO3 in 1 mL using the density:
mass of HNO3 = density of HNO3 × volume of HNO3
Given: density of HNO3 = 1.42 g/mL (grams per milliliter)
Volume of HNO3 = 1 mL
mass of HNO3 = 1.42 g/mL × 1 mL
mass of HNO3 = 1.42 g
Since 1L is equivalent to 1000 mL, the mass of HNO3 in 1L solution would be 1.42 g.
Now, let's move on to finding the mass of H2O:
Step 1: Calculate the density of water.
The density of water is approximately 1 g/mL.
Step 2: Calculate the mass of H2O in 1 mL using the density:
mass of H2O = density of H2O × volume of H2O
Given: density of H2O = 1 g/mL (grams per milliliter)
Volume of H2O = 1 mL
mass of H2O = 1 g/mL × 1 mL
mass of H2O = 1 g
Since 1L is equivalent to 1000 mL, the mass of H2O in 1L solution would be 1000 g.
To summarize:
- The mass of HNO3 in 1L is 1.42 grams.
- The mass of H2O in 1L is 1000 grams.
