Answer:
y = 3/2x + 1
Step-by-step explanation:
find the slope: goes up 9 over 6 => 9/6 = 3/2
the +1 is because the y intercept is not at (0, 0), it's at (0, 1)
I graphed it and got the same graph :)
4.6 moles in 187 grams of magnesium oxide (mgo).
<h3>What is mole explain with example?</h3>
- One mole is defined as the amount of substance containing as many elementary entities (atoms, molecules, ions, electrons, radicals, etc.) as there are atoms in 12 grams of carbon - 12(6. 023×1023).
- The mass of one mole of a substance equals to its relative molecular mass expressed in grams.
- The relative formula mass of a compound is calculated by adding together the relative atomic mass values for all the atoms in its formula.
- Moles are units used to measure substance amount. Chemistry (Single Science) Atomic structure.
To solve ,
number of moles is equals to the mass in grams divided by RFM
RFM=16+24.3=40.3
=187/40.3
=4.6 moles of MgO
