It's what you put :)
ΔH is the distance from the reactants (which would be E), to the products (which would be G or D)
I think it goes like this.
mass = 78.6 g
molar mass = 60.1 g/mol
amount (in mols) = mass/mol
78.6 g / 60.1 g/mol = 1.30782 mol
^^rounded to 3 sig figs, final answer = 1.31mol
Answer:
642.8g
Explanation:
NaCl has a molar mass of 58.44g/mol, which means one mole of NaCl has a mass of 58.44g.
11 moles of NaCl will have a mass of 642.8g.
11 mol NaCl x 58.44g = 642.8g
A homogeneous mixture<span> is a </span>type of mixture<span> in which the composition is uniform and every part of the solution has the same properties. A heterogeneous </span>mixture<span> is a </span>type of mixture<span> in which the components can be seen, as there are two or more phases present.</span>
