A) 0.875 M of MgBr2 is 0.875 mol/L
B) 23.7 mL = 0.0237 L
0.875 mol => 1 L
x mol => 0.0237 L
Cross multiply
1x = 0.875 × 0.0237
x = 0.0207 mol
>> In 23.7 mL of 0.875 M MgBr2 solution there is 0.0207 moles of MgBr2
C) Molar mass of MgBr2 (*) = 24.305 + (2 × 79.904) = 184.113 g/mol
184.113 g => 1 mol
x g => 0.0207 mol
Cross multiply
1x = 184.113 × 0.0207
x = 3.8111 g
>> 0.0207 moles of MgBr2 is equivalent to 3.81 g of MgBr2
>> In 23.7 mL of 0.875 M MgBr2 solution there is 3.81 g of MgBr2

Explanation:
During glycolysis is used glucose, ADP and pyruvate and produce ATP, water and NADH.
<h3>What is glycolysis?</h3>
Glycolysis is the first step of cellular respiration by which glucose is used to generate energy in the form of ATP.
Cellular respiration has three sequential steps, i.e., glycolysis, the Krebs cycle and oxidative phosphorylation.
Glycolysis is the cellular respiration step that generates 2 net high energy ATP molecules and 2 reduced NADH.
In conclusion, glycolysis uses glucose, pyruvate and ADP to generate ATP, water and Nicotinamide adenine dinucleotides (NADH).
