Answer:
0.454moles
Explanation:
Calculate the molar mass of AgBr
Ag=108
Br=80
Molar mass= 108+80
Molar mass=188g/mol
It's mole to gram question
2moles of Na2S2O3= 188g of AgBr
X moles of Na2S2O3=42.7g of AgBr
Cross multiply
188x=2×42.7
X= 85.4/188
X=0.454moles
A. Identical :) Hope it helps
The gram formula mass is Molar mass. The mass of 1.0 moles is :
3) 48.0 g
Answer:
yes its correct, temperature is a measure of energy particles have, the more energy the faster they move and the higher the temp
Explanation:
Answer:
Both electrons of Mg should be transferred to one O.
Explanation:
This is because metals like to lose electrons whereas non metals like to gain electrons in an ionic compound. MgO is an ionic compounds. So Magnesium being a metal in group 2 of periodic table, it wants to donate 2 electrons to get to the octet rule, so it donates its electrons and oxygen accepts them to fill its octet rule.
