A 25.0g tin sample was placed in boiling water at 99.5 C until it had the same temperature. Afterwards, the tin sample was place

Answer : The specific heat of tin is, 0.213 J/g.K

Explanation :

Formula used :

$q=m\times c\times (T_{final}-T_{initial})$

where,

q = amount of heat lost = -399.4 J

c = specific heat capacity of tin = ?

m = mass of tin = 25.0 g

$T_{final}$ = final temperature = $24.5^oC=273+24.5=297.5K$

$T_{initial}$ = initial temperature = $99.5^oC=273+99.5=372.5K$

Now put all the given values in the above formula, we get:

$-399.4J=25.0g\times c\times (297.5-372.5)K$

$c=0.213J/g.K$

Therefore, the specific heat of tin is, 0.213 J/g.K

A scientist wants to make a solution of tribasic sodium phosphate, Na3PO4, for a laboratory experiment. How many grams of Na3PO4

Harman [31]

Na₃PO₄ -----> 3Na(+) + PO₄(3-)
y-y.......................3y...........y

3y = 1.2
y = 0,4M

Na₃PO₄ -----> 3Na(+) + PO₄(3-)
0,4-0,4..............1,2..........0,4
0.........................1,2..........0,4

C = n/V
n = C×V
n = 0,4×0,65L
n = 0,26 mol Na₃PO₄

mNa₃PO₄: (23×3)+31+(16×4) = 164 g/mol

164g ----- 1 mol
Xg -------- 0,26 mol
X = 164×0,26
X = 42,64g Na₂SO₄
