Answer:
Explanation:
Molar mass of NaCl = 58.44
Molar mass of NaCl(58.44g) addding to 1000ml give rise to 1M solution always, this can be writtne as below
58.44----- >1000 ml ---> 1M
X gram ----360 ml ---0.35 M
X Gram= 58.44*360*0.35/1000*1 = 7.3 gram
hope you understood the solution

Answer:
17.04%
Explanation:
Actual Value = 173.1
Measured Value = 143.6
Percent error is obtained using the equation;
Percent error = (Measured - Actual) / Actual ]* 100
Percent error = [ (143.6 - 173.1) / 173.1 ] * 100
The absolute value of (Measured - Actual) is taken,
Percent Error = [29.5 / 173.1 ] * 100
Percent Error = 0.1704 * 100 = 17.04%
I think the Neolithic Revolution is the correct answer
