Answer:
Explanation:
When an atom has 2 or more isotopes, the average atomic mass (aam) depends on the mass of each isotope (mi) and the percentual abundance in nature of each isotope (abi). The average atomic mass can be calculated using the following expression:
Answer: 50 ml of 0.600 M of sulfuric acid will exactly neutralize the 100 ml of 0.300 M of barium hydroxide solution.
Explanation:
According to reaction 1 mole sulfuric acid neutralizes 1 mole oh barium hydroxide.
50 ml of 0.600 M of sulfuric acid will exactly neutralize the 100 ml of 0.300 M of barium hydroxide solution.
Luncar Eclipses are more common than solar eclipses because of the size of the Shadowmaker. The Earth is much bigger than the moon so it's easier to find the moon in the earth's shadow. In Solar Eclipses though, the Earth must Path through the moons relatively small shadows, and the 3 have to be aligned Just right to get a moon shadow focused on the Earth.
Few People get to view a total solar eclipse because when it finally happens, the part of Earth that is in the Darkest center of the shadow is somewhere small and randon
Hope this Helps :D

Answer:</h3>
3.11 moles
<h3>
Explanation:</h3>
We are given 56 g of water (H₂O)
Required to calculate the number of moles of water.
- The relationship between moles, mass and molar mass is given by;
- Moles = Mass ÷ molar mass
in this case;
- Mass of water = 56 g
- Molar mass of water = 18.02 g/mol
Therefore;
Moles of water = 56 g ÷ 18.02 g/mol
= 3.11 moles
Therefore, moles of water in 56 g will be 3.11 moles
