Determine the density (in g/mL) of a liquid given:
A beaker was weighed at 90. g, then 413.5mL of liquid was added and the new weight was 795 g.
The Specific heat of a substance is the energy (joules) required to raise one gram of substance by one degree celsius (units J/g °C).
Heating 225.0 cm3 of a solid from 36.1 °C to 74.3 °c takes 35850 J of energy. The density of the solid at 36.1 °C is 1.75 g/cm3.
What is the Specific Heat of the solid in this experiment
Sorry didn't realise I was on answer ment to post as a new questions.
795-90 = mass liquid.
density = mass/volume.
To determine the density of a liquid, you need to use the formula:
Density = Mass / Volume
In this case, the mass is the difference in weight of the beaker before and after adding the liquid, and the volume is the volume of the liquid.
Given:
Initial weight of the beaker = 90 g
Final weight of the beaker after adding liquid = 795 g
Volume of the liquid = 413.5 mL
Step 1: Calculate the mass of the liquid
Mass of the liquid = Final weight - Initial weight
Mass of the liquid = 795 g - 90 g
Mass of the liquid = 705 g
Step 2: Convert the volume to liters
Volume of the liquid = 413.5 mL
To convert mL to liters, divide by 1000.
Volume of the liquid = 413.5 mL / 1000 mL/L
Volume of the liquid = 0.4135 L
Step 3: Calculate the density
Density = Mass / Volume
Density = 705 g / 0.4135 L
Step 4: Convert the density to g/mL
To convert the density to g/mL, divide by 1 mL.
Density = 705 g / 0.4135 L
Density = 1703.155 g/L
Density = 1703.155 g/mL (approximately)
Therefore, the density of the liquid is approximately 1703.155 g/mL.
