Yes.
Yes!
2.5g/100ml = moles/1L First convert the ml into L. 2.5g/.100L = moles/1L Cross multiply. 25 moles/ 1L
every 100ml=1L so 7000ml will equal 70L
The solubility of NaCl at room temperature is 359g/L. (Wikipedia)To find out how much will dissolve in 100mL, first convert 359g/L to g/mL.359g/L x 1L/1000mL = 0.359g/mLThen multiply 0.359g/mL by 100mL0.359g/mL x 100mL = 35.9gYou should expect 35.9 grams of NaCl to dissolve in 100mL of water.
Scientifically, percentages can used to describe the number of grams of substance in 100ml. In this case, there are 2.4g in 1L... which is equivalent to 0.24g in 100mL... which is the same as a 0.24% solution
7p Begin by converting ml to litres: 100ml = 0.1l 1l = 70 p .1l = x To solve for x, cross multiply then divide. 70p * .1 litre / 1 litre = 7p (While it would be faster to divide by ten upon recognizing the pattern, always cross multiply because the numbers will not always perfectly work out, especially when decimals are involved)
The Molecular Weight of NaCl = 58.5 So to make 1L of 4M NaCl solution you need 4*58.5=234g of NaCl So to make 100mL of the above solution you need 23.4 grams of NaCl
If you need to make just 100mL, then you need 1 tenth of a liter that is 5M. If you were to make 1L of 5 molar NaCl, you would need 5 times the molar mass of NaCl (58.44g/mol) dissolved in 1L of water. Thus for 1L of a 5M solution you need 5 * 58.44g, or 292.2 grams of NaCl. However, since we only want 100mL, which is 1/10 of a Liter, we also only need 1/10 the amount of NaCl, or 292.2 / 10, which is 29.22g. So, measure out 29.22g NaCl, and dissolve completly in a volume less than 100mL, say 80mL, then bring the final volume up to 100mL. You now have 100mL of a 5M NaCl solution.
For the cabin luggage, each bottle should be no more than 100ml and a max of 1L altogether. Eg, max of 10 bottles of 100 ml each one.
