Answer:
2.52kg
Explanation:
80mm = 8 cm
0.15m = 15 cm
volume of the container = 10m × 8cm × 15cm
= 1200 cubic centimetres
mass = density × volume
= 2.1 × 1200
= 2520g
2520/ 1000
= 2.52kilograms
If you cook something you're making a chemical change to whatever it is you are cooking lol that is one way. hope this helps:))))))))))
Answer:
The mass of ammonia (NH3) that contains hydrogen atoms is g.
Explanation:
As atoms of hydrogen = 1 mole of the hydrogen atom
Therefore, atoms of hydrogen moles of the hydrogen atom.
Now, there are 3 moles of hydrogen atoms in 1 mole of ammonia .
As the mass of 1 mole of ammonia is 17g, so
when there are 3 moles of hydrogen atoms, then the mass of ammonia = 17 g
Therefore, when there are moles of hydrogen atoms, then the mass of ammonia g.
Hence, the mass of ammonia that contains hydrogen atoms is g.
Elements in the same group share the same number of valence electrons.
Answer:
The gravitational pull of the moon is lower than the earth's, because it is smaller
Explanation:
According to the universal law of gravity, the acceleration of gravity on a planet is directly proportional to the mass of the planet and inversely proportional to its radius.
If moon is one-sixth the size of the earth, this implies that its radius is lower than the radius of earth. According to the law , this implies that the acceleration of gravity on moon will be lower than on earth.
