Answer:
in short weight
Explanation:
weight is mass x gravitational pull on an object
Answer:
The number of molecules = 2.6408 molecules
Explanation:
To determine the number of molecules in water, we need to determine how many moles of water we have
Water has a molar mass of 18.015g/mol, this means that one mole of water molecules has a mass of 18.015g
To find the number of molecules,
7.9g * 1 mole H2O/ 18.015g
= 0.4385mole of H2O
Using avogadro number,
0.4385 H2O * 6.022* 10^23molecules/ 1 mole of H2O
That's 0.4385 H2O multipled by 6.022*10^ 23 molecules divided by 1 mole of H2O
Which gives == 2.6408 molecules
Living things are composed of cells, Living things have different levels of organization, Living things use energy, Living things respond to their environment, Living things grow, Living things reproduce, Living things adapt to their environment. Hope that helped!
Answer:
<u><em>DUDE YOUR ANSWER IS:</em></u>
Explanation:
<u><em>GIVEN BY YOU:</em></u>
[H+]=(1*10^-6)
Taking negitive log on both sides we get,
-㏒[H+]=-㏒(1*10^-6)
now by power rule of exponent, and also we know that
-㏒[H+]=PH so we get
PH= -(-6)(log(10))
as we know log(10)=1 hence by putting we get
PH=6
<u><em>acidic or a basic solution:</em></u>
as PH<7 hence its acidic
