Answer:
= $ 4344.05
Step-by-step explanation:
Using the formula
A = P (1 +r/n)^nt
Where A is the amount accumulated, P is the principal amount, n is the number of interest periods, t is the time taken in years.
A = $4369.20
r = 0.033
n = 4
t = 21/12
Therefore;
$4369.20 = P ( 1 + 0.033/4)^ (21/12×4)
$4369.20 = P (1.000825)^7
$4369.20 = 1.005789 P
P = $4369.20/1.005789
<u> = $ 4344.05</u>
Answer:
16.7
Step-by-step explanation:
is the right answer
Answer:
I'm on that to and trust me I don't know
Step-by-step explanation:
$56.25, since 25% off can also be written as ÷4, since 25 is a quarter. 75÷4=18.75
75-18.75=56.25. Therefore, the answer is $56.25
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
