1:1
8×2=16
Answer:
2h+02=h20
Explanation:
2 in front of h on left side
2 in front of h on right side
the answer is dure light I'm not sure of this answer ,but it might be to go with .
Answer:
3.2×10^-3 mol
Explanation:
The equation for molarity is M= n/L. Where "M" is Molarity, "n" is the number of moles of solute, and "L" is the total liters in solution.
The question gives you the volume in mL, so to convert "mL" to "L" you need to divide by 1000. (6.70mL/ 1000L)= 0.0067L.
Now you can plug the numbers into the equation. 0.480M= n/ 0.0067L), multiply (0.480M×0.0067L)= 0.003216 mol. The scientific notation is 3.2×10^-3, 10^-3 because you move the decimal back three times and 3.2 because there are 2 sig figs.
