Answer:
d = 8 g/mL
Explanation:
Given data:
Mass of metal = 24 g
Volume of eater = 45 mL
Volume of water + metal = 48 mL
Density of iron metal = ?
Solution:
Volume of metal:
Volume of metal = volume of water+ metal - volume of water
Volume of metal = 48 mL - 45 mL
Volume of metal = 3 mL
Density of metal:
d = m/v
d = 24 g/ 3 mL
d = 8 g/mL
.15 liters of normal saline will drip into the patient's IV per hour.
N= number of molecules
n= 2.3x10^23/6.022x10^23
= 0.381 mol
Now,
M= molar mass in g/mol
m= mass in grams
m=nxM
=0.381 molx137 g/mol
= 52.197g
So, the correct answer should be C
