Explanation:
mass of MgCl = 257.26 grams
Answer:
A
Explanation:
Protons and neutrons make up nearly all the mass of an atom, and each is worth 1 amu. Each atom of an element has a mass measured in amu; thus, its weighted average, or atomic mass, is measured in amu.
Electrons are way way way....lighter so protons and neutrons are taken into account when doing atomic mass.

Answer:
m = 575 g
Explanation:
Given data:
Volume of solution = 0.500 L (0.500×1000 = 500 mL)
Density of glucose solution = 1.15 g/mL
Mass of glucose solution = ?
Solution:
Formula:
d = m/v
d = density
m = mass
v = velocity
Now we will put the values in formula.
1.15 g/mL = m/500 mL
m = 1.15 g/mL × 500 mL
m = 575 g
