Answer:
Explanation:
1. Calculate the moles of CoF₂ needed
2. Calculate the mass of CoF₂
This easy bro there is only one answer Gravity
but here my advance word
Sometimes the gravity of big objects would capture smaller ones in orbit. This could be one way the planet acquired the moon
The answer is the coefficient is "1".
C₅H₁₀, now you see that there is no number with this and when there is no number or digit, it means the coefficient is one.
we use the coefficients to balance the equation of the reaction in such a way that number of the atoms of the elements in the reactants are equal to the number of atoms of different elements in the product, so that both sides are equal and balanced.
Answer:
4.998 × 10²⁴ amu
Explanation:
Given data:
Mass of substance = 8.3 g
Atomic mass unit = ?
Solution:
The mass of one mole of substance is equal the gram per mole of that substance.
atomic mass unit = g/mol
For 8.3 g:
8.3 × 6.022×10²³
4.998 × 10²⁴ amu
The number 6.022 × 10²³ is called Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
