Answer: The moles of HCl are 0.0244
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute = ?
= volume of solution in ml
Now put all the given values in the formula of molality, we get
Therefore, the moles of HCl are 0.0244
Answer:
C. Between 0 and 1 seconds
Explanation:
Since 0 - 1 seconds the car accelerates to 20mph. The rest each second the car accelerates 5mph.
M{(NH₄)₂Cr₂O₇}=2A(N)+8A(H)+2A(Cr)+7A(O)
M{(NH₄)₂Cr₂O₇}=252.065 g/mol
M(Cr)=51.996 g/mol
m{(NH₄)₂Cr₂O₇}/M{(NH₄)₂Cr₂O₇}=m(Cr)/2M(Cr)
m(Cr)=2M(Cr)m{(NH₄)₂Cr₂O₇}/M{(NH₄)₂Cr₂O₇}
m(Cr)=2*51.996*35.8/252.065=14.770 g
m(Cr)=14.770 g
Answer:
Un atomo es el parto pequeño de un elemento y es el bloque de construcción de la materia. Puede ser conocido como neutrón, protón o electrón.
Except for the Middle East :)
