m=3gram AnsIn order to convert Sodium Hydroxide, otherwise known as NaOH to percent concentration you will need to use the formula that 1 L of 0.125 M NaOH contains 0.125 mol of NaOH.
The percent concentation is 40 g NaOH/100 g water.
n = (100n)%therefore you would write0.0014 as 0.14%
n = 6050 = 100 Using the criss cross multiplication trick we get 50X60=3000 and 100 X n=100n 3000 = 100n 100 = 100 So 3000÷100=30 and 100n÷100=n. n=30 or 60% of 50 is 30
10.515% of 70: put n over 70 equals 15 over 100n ----------15--- equals ---- then cross multiply n x 100 and 15 x 7070---------100which would be 100n and 1050then divide100n --------1050------ equals ------- n equals 10.5%100 -----------100
10% of 60.0 is 6 (just move the decimal point one place to the left)60% = 6x10% = 6x6 = 36%Better still:6/10 of 60 [or 3/5 of 60] can be expressed as 0.6 x 60.00 = 36.00.The double word typo led original anwer to misread the last figure, 60, as 60%.
If: 100n = 300 Then divide both sides of the equation by 100 to find the value of n:- n = 3
sqrt(101N)
100N is 22.481 pounds.
100N roughly on earth
The acceleration is 0. That also means that the net force is 0N since the gravity Force is 100N down and the bag of nails is 100N, the air resistance must be 100N up to balance it out and create the net force of 0N

100N is 10.2 kilos or 22.48 pounds.
