The molecular weight of the molecular compound is
x= 105.57 g/mol
<h3>What is the molecular weight of the molecular compound?</h3>
Generally,a the equation for Mole of molecular compound is mathematically given as
Mm= mass / molar mass
Therefore
Mm= 0.333 g / x
the equation for Morality
M = mole of solute / mass of solvent
M= 10 / x
the equation for change in temp dt
dt= K* morality
Therefore
x = (5.12 *10) / 0.485
x = 105.57 g/mol
In conclusion, molecular mass of molecular compound
x= 105.57 g/mol

Answer:
C) 2.99 cm^3
Explanation:
ρ=m/V
V=m/ρ=59.2/19.8=2.99 cm^3
Answer;
= g/cm^3
Explanation;
-Density is the mass per volume of a substance, or the weight per volume of an object. The Metric System is a type of system of measuring that uses only one root word for each basic dimension, such as, -gram for mass or -meter for distance.
-Metric system densities are usually in the units of mass per volume, such as g/cm^3 (gram per cubic centimeter). Where grams represents the units of mass and cm^3 represents the volume.
Answer:
Lead(II) sulfate
Explanation:
This looks like a double displacement reaction, in which the cations change partners with the anions.
The possible products are
Pb(NO₃)₂ (aq)+ Na₂SO₄(aq) ⟶PbSO₄(?) + 2NaNO₃(?)
To predict the product, we must use the solubility rules. Two important ones for this question are:
- Salts containing Group 1 elements are soluble.
- Most sulfates are soluble, but PbSO₄ is an important exception.
Thus, NaNO₃ is soluble and PbSO₄ is the precipitate.
A.) In the beginning the universe was too hot for atoms to exist.
Because choice b,c,and d are all part of the big bang theory.
