Question
evidence:
| mass of liquid (g) | volume (ml) | density (g/ml⁻¹) | substance | |
|---|---|---|---|---|
| liquid b | type answer | 10 ml | type answer | type answer |
| liquid c | type answer | 10 ml | type answer | type answer |
To solve for the mass, density, and identify the substance, we need additional information (e.g., known density values of common substances or the mass of the liquid). Since the problem as presented is incomplete (no specific values for mass or known density to calculate or identify), we can't proceed with calculations.
If we assume we have the mass of the liquid (let's say for Liquid A, mass = \( m \) grams), we can use the density formula \(
ho = \frac{m}{V} \), where \( V = 10 \, \text{mL} \). Then we compare the calculated density to known densities of substances (e.g., water has a density of \( 1 \, \text{g/mL} \), ethanol ~ \( 0.789 \, \text{g/mL} \), etc.) to identify the substance.
For example, if Liquid A has a mass of \( 10 \, \text{g} \):
Step 1: Recall the density formula
The formula for density is \(
ho = \frac{m}{V} \), where \(
ho \) is density, \( m \) is mass, and \( V \) is volume.
Step 2: Substitute the values
Given \( m = 10 \, \text{g} \) and \( V = 10 \, \text{mL} \), we substitute into the formula: \(
ho = \frac{10 \, \text{g}}{10 \, \text{mL}} \)
Step 3: Calculate the density
\(
ho = 1 \, \text{g/mL} \), which is the density of water, so the substance could be water.
But since the problem doesn't provide specific mass values, we need more details. Please provide the mass of each liquid (or other relevant information) to complete the calculations and identify the substances.
