Answer:
95.2 - 40.8 = 54.4 g of oxygen
number of moles = mass (g)/ Mr
no. of moles of carbon = 40.8/12 = 3.4
no. of moles of oxygen = 3.4
divide both by smallest value which is 3.4 and you’ll get 1 mole of carbon and 1 mole of oxygen therefore the empirical formula is CO
Explanation:
hope this helps :)
Answer:
Kilogram
Explanation:
The metric system is the Kilogram, meter, second system. These are fundamental quantities of the metric system.
Kilogram, the unit of mass always carries the prefix 'kilo' in its SI unit. Kilogram is the SI unit of mass. Hence, the fundamental unit on the metric system that always has a prefix in front of it is kilogram.
Answer:
Q = 87.31cal
Explanation:
Mass = 57.8g
T1 = 17.0°C
T2 = 43.5°C
Specific heat capacity (c) = 0.057cal/g°C
Q = MC∇T
Q = M*C*(T₂ - T₁)
Q = 57.8 * 0.057 * (43.5 - 17.0)
Q = 3.2946 * 26.5
Q = 87.306 cal
Q = 87.31cal
