Answer:
volume is 7.0 liters
Explanation:
We are given;
- Molarity of the aqueous solution as 2.0 M
- Moles of the solute, K₂S as 14 moles
We are required to determine the volume of the solution;
We need to know that;
Molarity = Moles ÷ volume
Therefore;
Volume = Moles ÷ Molarity
Thus;
Volume of the solution = 14 moles ÷ 2.0 M
= 7.0 L
Hence, the volume of the molar solution is 7.0 L
Mass is related to weight. It measures the resistance of the substance to acceleration when a net force is applied.
Therefore: armful of lead has more mass
volume measures the amount of 3-dimensional space that an object occupies.
Therefore: kilogram of feather has more volume as it is less dense.
density is the mass per unit volume. Since armful of lead has more mass than a handful of feathers, while kilogram of feather has more volume than a kilogram of lead.
Therefore: kilogram of lead has higher density.
Answer:
Explanation:
Given that,
The wavelength of a microwave is 7.42 mm or 0.00742 m
No. of photons, n = 359
We need to find the energy produced by this no of photons. It can be given by the formula as follows :
or
So, the required energy is 
.
The volume of NaOH solution is 0.532 L.
<em>Step 1</em>. Calculate the <em>moles of NaOH</em>.
Moles = 11.5 g NaOH × (1 mol NaOH/40.00 g NaOH) = 0.2875 mol NaOH
<em>Step 2</em>. Calculate the <em>volume of NaOH</em>
Volume = 0.2875 mol NaOH × (1 L NaOH/0.540 mol NaOH) = 0.532 L
The answer is chemical. Flammability is a chemical property
