Find the molar mass in grams of <br> CaSO4 * 2H20<br> grams
adoni [48]

Answer:

172 g/mol

Step-by-step explanation:

CaSO4 . 2H2O

Atomic mass of

Ca = 40

S = 32

O = 16

H = 1

Molar mass = 40 + 32 + (16×4) + 2{(1×2)+16}

= 72 + 64 + 2(18)

= 136 + 36

= 172 g/mol

Question 3 (Multiples and Factors] Three numbers are given below. Use prime factorisation to determine the HCF and LCM 1848 132
Ilia_Sergeevich [38]

Prime factorization involves rewriting numbers as products

The HCF and the LCM of 1848, 132 and 462​ are 66 and 1848 respectively

<h3>How to determine the HCF</h3>

The numbers are given as: 1848, 132 and 462

Using prime factorization, the numbers can be rewritten as:

1848 = 2^3 * 3 * 7 * 11

132 =  2^2 * 3 * 11

462 = 2 * 3 * 7 * 11

The HCF is the product of the highest factors

So, the HCF is:

HCF = 2 * 3 * 11

HCF = 66

<h3>How to determine the LCM</h3>

In (a), we have:

1848 = 2^3 * 3 * 7 * 11

132 =  2^2 * 3 * 11

462 = 2 * 3 * 7 * 11

So, the LCM is:

LCM = 2^3 * 3 * 7 * 11

LCM  = 1848

Hence, the HCF and the LCM of 1848, 132 and 462​ are 66 and 1848 respectively

When given an algebraic expression involving subtraction, why is it best to rewrite the expression using addition before identif
Ray Of Light [21]
Usually when you do expressions involving subtraction you can do Keep, Change ,Change
That means you keep the sign of the first number and change the other two signs.
It is best you rewrite the expression to addition because a lot of people don't do well with subtracting .

Can you double a square with a straightedge and a compass?
sergejj [24]
I'd say yes.  If you use the diagonal as a reference.  Take the square and set your compass to the width of the diameter of the square.  Now put it on the page and mark a point.  Put the point of the compass on that mark and make another mark.  Now you can connect the two marks with the straight edge and you have a line that, if you made a square with sides that long, it'd have 2x the area of the first one.  That's because the diagonal is the square root of 2 larger than one side.  Square the square root of 2 and you've got 2.  You lust need to make a perpendicular line to the first one to get the box going.
