Answer:
41.2 lb/gal
Explanation:
Step 1: Given data
Density of iodine: 4.94 g/mL
Step 2: Convert the mass to grams
We will use the conversion factor 1 lb = 454 g.
4.94 g/mL × (1 lb / 454 g) = 0.0109 lb/mL
Step 3: Convert the volume to gal
We will use the conversion factors 1 gal= 3.785 L and 1 L = 1,000 mL.
0.0109 lb/mL × (1,000 mL/1 L) × (3.785 L/1 gal) = 41.2 lb/gal
) Mass divided by density
Answer:
given that
....the mass of the metal is 20g(0.02kg)
....specific heat capacity(c) is 0.4J/g°C
....ΔT=??
heat(Q)=3.9KJ(3900J)
Q=mcΔT
ΔT= Q/mc
.....=3900÷(20g x 0.4J/g°C)
.....=487.5°C
Answer:1:water molecule 2:E coli bacteria 3:skin cells ,4:grain of salt 5:human
Explanation:
There u go buddy
Answer:
The answer is 5 mol
Explanation:
Number Of Moles = Mass Of Substance ÷ Mass Of One Mole
Mass of NaOH = Molar Mass of Sodium + Oxygen + Hydrogen
23 + 16 + 1
40 g/mol
Number of Mole = 200/40 = 5 mol
Thus, The number of Moles in 200 grams of Sodium hydroxide is 5 mol
