Answer:THIS IS NOT THE ANSWER
is this for the chemistry A final 10th grade for connexus (unit7 lesson 2)?
Explanation:
Answer:
Explanation:
First convert the grams of Calcium Bromide to moles by using the atomic weight. Then use the formula for molarity, which is moles per liter.
CaBr2 = 199.9 g/mol
10/199.9 = 0.05 moles of CaBr2
x = 0.1L or 100mL
A is your answer The ratio of females to males
Answer:
44.4g
Explanation:
First we must find the moles of argon.
To do this, divide the number of atoms by Avogadro's number (6.022 ×10^23)
n= (6.7 × 10^23)/(6.022 × 10^23)
n=1.11258718034
Now to find mass, we complete the calculation
m= n × MM
where
m is mass
n is moles
MM is molecular mass
m= 1.11258718034 × 39.948
m= 44.4456326802
m= 44.4g
Answer:
Surface area of the reactants
Explanation:
If the reactants say Cu is in the powdered form, it reacts very quickly, otherwise the reaction will be delayed
