Answer:
492.6g
Explanation:
Given parameters:
Number of moles of MgSO₄.7H₂O = 2moles
Unknown:
Mass = ?
Solution:
To find the mass of this compound;
Mass = number of moles x molar mass
Molar mass of MgSO₄.7H₂O = 24.3 + 32 + 4(16) + 7[2(1) + 16]
= 246.3g/mol
Mass = 2 x 246.3 = 492.6g
Answer:
I think it might towering cumulonimbus or cumulonimbus
<span>There are three process by which the heats are transferred.They are conduction,convection & radiation. The concept of thermos flax designed to avoid all these process,that is why we are able to keep at required temp without loss are gain of temp. The convection is a method by which the heat is transfer through third media.Please look in to my site for earth section.The heat at mandrill is transferred to lithosphere and to crest by the medium called magma. This is carrying the heat from inner layer to outer core of the earth.How the egg immersed in hot water is boiled is the same process.</span><span />
