Molar mass of aspirin =180. So, moles of aspirin = 500 × 1 0 − 3 / 180 = 2.78 × 1 0 − 3 = 278 × 1 0 −
<u>Answer:</u> 1.0 kilograms.
<u>Explanation:</u>
One kilogram is equal to a thousand grams.
Supposing x to be the number of kilograms equal to one thousand and eight grams, we can write it as:
1 kg = 1000 grams
x kg = 1008 grams
To solve for x, we can simply divide 1008 grams by 1000 thousand grams to get the answer.
x = 1008 / 1000
x = 1.008
Rounding this value to the nearest tenth, it will become 1.0 kilograms.
when the metal is lost heat and the calorimeter of water is gained the heat
and when the heat lost = the heat gained so,
(M*C*ΔT)m = (M*C*ΔT)w
when Mm= mass of the metal = 30 g
Δ Tm = (80-25) = 55 °C
and Mw = mass of water = 100 g
Cw is the specific heat of water = 4.181 J/g.°C
ΔTw = (25-20) = 5 °C
so by substitution:
∴ 30* Cm*55 = 100 * 4.181 * 5
∴Cm (specific heat of metal) = (100*4.181*5)/(30*55)
∴C of metal = 1.267 J/g.°C
