An empirical formula is the "reduced" version of a molecular formula. For example, CH3 is the empirical formula for C2H6, C3H9, C4H12, and so forth. The difference in subscripts between an empirical formula and molecular formula is given by the constant n. If n is a whole number, this means the numerator is the molecular formula. So the answer is D. <span>subscript of C in molecular formula = n  subscript of C in empirical formula. This can be rewritten as:
n = subscript of C in molecular formula/subscript of C in empirical formula</span>
Because no one else can have the same fingerprint as another person. Each fingerprint is individual and unique.
Answer:
na
Explanation:
because it has more atomic radius in it
The volume will be one third of the original volume of an ideal gas.
Boyle’s law depicts the relationship between the pressure ,volume and the temperature of a gas. Boyle’s law states that the pressure of a gas is inversely proportional to its volume at a constant temperature.
P ∝ 1 / V
Or, PV = k
When the temperature is kept constant.
According to the question, when the pressure is increased from 2 atm to 6 atm , the pressure is increases thrice ,hence the volume will decrease three times simultaneously of the original volume of 1 mol of an ideal gas.
The equation of the Boyle’s law is; P1V1 = P2V2

Answer: -
37.5 g of NaCl are in 250 g of a 15.0% (by weight) solution.
Explanation: -
Total mass = 250 g
Percentage of NaCl = 15.0 %
= 
Thus 
= 
Number of grams of NaCl present = 
= 37.5 g
