Answer:
Mass = 3732.62 g
Explanation:
Given data:
Number of formula units = 8.53×10²⁴
Mass of sample = ?
Solution:
1 mole of any substance contain 6.022×10²³ formula units.
8.53×10²⁴ formula units ×1 mol / 6.022×10²³ formula units
1.42×10¹ mol
14.2 mol
Mass of magnesium phosphate:
Mass = number of moles × molar mass
Mass = 14.2 mol × 262.86 g/mol
Mass = 3732.62 g
Answer:
➳ You can use the <u>centrifugation</u> method to separate chemicals present in the blood.
The answer is B) Electrical outlets contain metal wires that are good conductors of electricity. In order to promote electrical safety, the parents covered the outlets with plastic, an insulator that prevents electrical current from flowing to another object.
