Explanation:
From the question we are told that:
Amount of sand in percentage 
Sample size
Note:After being dumped in the river repeatedly the sugar melts away leaving behind the insoluble sand
Generally the equation for Amount of sand content is mathematically given by



Therefore
After drying, the mass of the contents of the bag equals

I think that the answer is 4, but i dont know
Some material from meteors lingers in the mesosphere, causing this layer to have a relatively high concentration of iron and other metal atoms. Very strange, high altitude clouds called "noctilucent clouds" or "polar mesospheric clouds" sometime form in the mesosphere near the poles.
I really hope this helps! I wish you the best of luck!
Answer:
0.962 atm.
97.4 kPa.
731 torr.
14.1 psi.
97,434.6 Pa.
Explanation:
Hello.
In this case, given the available factors equaling 1 atm of pressure, each required pressure turns out:
- Atmospheres: 1 atm = 760 mmHg:

- Kilopascals:: 101.3 kPa = 760 mmHg:

- Torrs: 760 torr = 760 mmHg:

- Pounds per square inch: 14.69 psi = 760 mmHg:

- Pascals: 101300 Pa = 760 mmHg:

Best regards.
