5 grams of salt in 75 grams of water = 5 grams of salt in 80 grams of the solution.So the mass concentration = 5/80 = 100*5/80% = 6.25%5 grams of salt in 75 grams of water = 5 grams of salt in 80 grams of the solution.So the mass concentration = 5/80 = 100*5/80% = 6.25%5 grams of salt in 75 grams of water = 5 grams of salt in 80 grams of the solution.So the mass concentration = 5/80 = 100*5/80% = 6.25%5 grams of salt in 75 grams of water = 5 grams of salt in 80 grams of the solution.So the mass concentration = 5/80 = 100*5/80% = 6.25%
You have to do a conversion to your local time. If you live in the GMT + 5 (Eastern standard time) and wish to find out when an even in GMT + 1 is at you would add four hours. It is the difference between the time zones. If you want to find out what time an event is at that is GMT - 4 you would add 9 hours, because 5 - -4 is 5+4 = 9. That is the general rule, your GMT - Other TimeZone. GMT + 5 - GMT - 4 = 5 - -4 GMT + 5 - GMT + 1 = 5 - 1 Then the result is added to the time.
4 / (4/5) = 4 * (5/4) = 4*5/4 = 5
5 1/5 - 4 4/5 = 4 6/5 - 4 4/5 = 2/5
6*4/5 = 24/5 = 44/5 or 4.8
