Answer:
The answer to your question is 71.22 g
Explanation:
Data
Density = 19.3 g/cm³
Volume = 0.00369
mass = ?
Formula
Density = 
Solve for mass
mass = density x volume
Process
1.- Convert volume from liters to cubic centimeters
1 l ---------------- 1000 cm³
0.00369l --------- x
x = (0.00369 x 1000 ) / 1
x = 3.69 cm³
2.- Substitution
mass = 19.3 x 3.69
3.- Simplification and result
mass = 71.22 g
Answer:
The concentration of dilute solution is 0.72M
Explanation:
According to the given question
V1=30 ml
S1 = 12 M
V2= 500 ml
then S2 =?
we all know that V1S1=V2S2
or S2= V1S1÷V2
or S2 = 30×12÷500
or S2= 360÷500
or S2 =0.72 M.
The concentration of dilute solution is 0.72 M
Answer:
Explanation:
Mass is how much an object weighs . Volume is the amount of space the object takes up
Answer:
Option B. PV = nRT.
Explanation:
From the above,
C = PV / T. (1)
But, C is directly proportional to n, where R is the gas constant i.e
C & n
C = nR
Substituting the value of C into equation (1), we have:
C = PV / T
nR = PV / T
Cross multiply to express in linear form
nRT = PV
Therefore,
PV = nRT
