Answer:
1.196 M NaOH
Explanation:
Molarity = moles/Volume (L)
moles NaOH = mass NaOH/MM NaOH = 12/40.01 = 0.299 moles NaOH
Volume solution = 250 mL = 0.250L
M = 0.299/0.250=1.196 M NaOH
LBr is ionic compound because k for potassium is metal which means it’s on the left side of the periodic table and Br which is bromine is a non metal which means is on the right side of the periodic table.
In Conclusion when a non metal and metal come together the are called ionic compound

Answer:</h3>
1.0177 g/cm³
<h3>
Explanation:</h3>
We are given;
- Mass of the cube = 40 grams
- Length of the cube = 3.4 units
We are required to get the density of the cube;
- Assuming the length is 3.4 cm
- The volume of the cube is given by l³
Thus, Volume of the cube = 3.4 cm × 3.4 cm × 3.4 cm
= 39.304 cm³
But, density = Mass ÷ volume
= 40 g ÷ 39.304 cm³
= 1.0177 g/cm³
Therefore, the density of the cube is 1.0177 g/cm³
