Answer:
The mass of aluminum is 26.982 g/mol.
Step-by-step explanation:
The molar mass of an element is the mass in grams of 1 mole of the element. It is determined by taking the atomic weight of the element on the periodic table, and writing it as g/mol.

Answer:
m + 180
———————
4
Step-by-step explanation:
1
Simplify —
4
Equation at the end of step 1 :
1
45 + (— • m)
4
Step 2 :
Rewriting the whole as an Equivalent Fraction :
2.1 Adding a fraction to a whole
Rewrite the whole as a fraction using 4 as the denominator :
45 45 • 4
45 = —— = ——————
1 4
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
45 • 4 + m m + 180
—————————— = ———————
4 4
Final result :
m + 180
———————
4
Answer:
x is 23
Step-by-step explanation:
Fx or just x is equal to 23
Probability=number of specific outcomes/number of total possible outcomes...there are 16 pieces in all.
So the probability of picking a king is 1/16
And the probability of picking a pawn is 8/16=1/2
The probability of these two events happening in a row is:
P(k)*P(p)=(1/16)(1/2)=1/32
