How to find the weight of h2o-(water).

[VELISA07103]

MY SON HAS A 6TH GRADE SCIENCE QUESTION FOR HOMEWORK-CAN YOU FIND THE WEIGHT OF 50 MI OR ML OF H20? HE SAYS THEY ARE LEARNING HOW TO USE A TRIPLE BEAM SCALE IN CLASS. HOW WOULD HE FIND THIS ANSWER AT HOME? PLEASE HELP. THANK YOU. NO E-MAILS PLEASE.

First lesson: caps lock is a bad key, try to use proper capitalisation (to the longterm forum members here, I know that I'm not particularly good at it either, but I just tend to miss them out.)

 

Second. If they are using triple beam scales then why can't he just measure out 50ml and weigh it? Remembering of course to subtract the weight of the container.

 

If that isn't an option then he can use the density of water. 1 litre weighs roughly 1000 grams(This depends on temperature but for the level your son is this will be fine).

 

It is a simple calculation here as we can see that 1 thousandth of a litre(1 ml) weighs 1 gram.
