With your mind. Boom. Lol I'm sorry I don't know I just need points
Answer:
hecto-
Explanation:
The prefix value of 100 is hecto therefore 100X can be called hecto-x.
Such prefixes as this are expressed in the order of tens. Units generally exists scientifically in multiples and submultiples form using prefixes.
For the multiples:
10 deca(da)
100 hecto(h)
1000 kilo(k)
1000000 mega(M)
1000000000 giga(G)
No its a example of heterogeneous mixture
Given the mass of
=25.6 g
The molar mass of
=390.35g/mol
Converting mass of
to moles:
![25.6 g Al_{2}(S_{2}O_{3})_{3}*\frac{1molAl_{2}(S_{2}O_{3}}{390.35 gAl_{2}(S_{2}O_{3}} =0.0656molAl_{2}(S_{2}O_{3}](https://tex.z-dn.net/?f=25.6%20g%20Al_%7B2%7D%28S_%7B2%7DO_%7B3%7D%29_%7B3%7D%2A%5Cfrac%7B1molAl_%7B2%7D%28S_%7B2%7DO_%7B3%7D%7D%7B390.35%20gAl_%7B2%7D%28S_%7B2%7DO_%7B3%7D%7D%20%3D0.0656molAl_%7B2%7D%28S_%7B2%7DO_%7B3%7D)
Converting mol
to mol S:
![0.0656mol Al_{2}(S_{2}O_{3})_{3}*\frac{6molS}{1mol Al_{2}(S_{2}O_{3})_{3}}=0.3936 molS](https://tex.z-dn.net/?f=0.0656mol%20Al_%7B2%7D%28S_%7B2%7DO_%7B3%7D%29_%7B3%7D%2A%5Cfrac%7B6molS%7D%7B1mol%20Al_%7B2%7D%28S_%7B2%7DO_%7B3%7D%29_%7B3%7D%7D%3D0.3936%20molS)
Converting mol S to atoms of S using Avogadro's number:
1 mol = ![6.022*10^{23}atoms](https://tex.z-dn.net/?f=6.022%2A10%5E%7B23%7Datoms)
![0.3936mol S *\frac{6.022*10^{23}atoms S}{1 mol S}=2.37*10^{23} S atoms](https://tex.z-dn.net/?f=0.3936mol%20S%20%2A%5Cfrac%7B6.022%2A10%5E%7B23%7Datoms%20S%7D%7B1%20mol%20S%7D%3D2.37%2A10%5E%7B23%7D%20S%20atoms)
Mass to moles
5.2 mol/Ca(no3)2 to mol
5.2 mol/Ca(no3)2 / molar mass
5.2 mol/Ca(no3)2 / 164.1= 0.032 g/Ca(no3)2
