Answer:
Explanation:
pressure of dry nitrogen gas at 20° = Partial pressure of nitrogen and partial pressure of water at that temperature .
The pressure of dry nitrogen gas= total pressure - vapour pressure of water at 20°C
= 200 k Pa - 2.34 k Pa
= 197.66 kPa.
Answer:
0.98 g/mL
Explanation:
We know that the density of an object can be measured by dividing its mass (g) to its volume (mL).
Formula
D=m/v
Given data:
Mass= 10.00 g
Volume= 10.2 mL
Now we will put the values in formula:
D= 10.00 g/ 10.2 mL= 0.98 g/mL
So the density of corn syrup is 0.98 g/mL.
