Effectus [21]

Labels must clearly identify the chemical and include information on its hazards, plus instructions and information on its safe storage, handling, use, and disposal.

What does the information on the chemical label indicate?

The chemical label indicates the following information.

Product Identifier: The method used to identify the chemical (in the ingredient disclosure). On the label, include the complete chemical name or number that is used for the hazardous product. Both the label and SDS must have the same information. Abbreviations for chemicals are not accepted.

Signal Words: Assigned to a GHS hazard class and category, "Danger" or "Warning" are used to underline hazards and show the relative level of severity of the hazard.

Danger Statements: Typical expressions that are associated with a hazard class and category and that define the hazard's characteristics. On a label, there must be mention of every danger that applies.

Precautionary Statements: A term that describes actions that should be performed to reduce or eliminate negative effects brought on by exposure to or inappropriate storage of a substance.

A student measures the mass of a 6.0 cm3 block of brown sugar to be 10.0 g. What is the density of the brown sugar?
Alex17521 [72]

Answer:

1.67g/cm3

Explanation:

The formula for density is d=\frac{m}{v} . The m variable stands for mass and the v variable stands for volume.

The mass of the brown sugar is 10.0g and the volume is 6.0cm3, so we can plug those values into the equation.

d=\frac{10g}{6cm^{3} }

d=1.67\frac{g}{cm^{3} }

Rounded to 3 significant figures, the density of the block of brown sugar is 1.67 g/cm3. If the mass is in grams and the volume is in cm3, the unit for the final answer is \frac{g}{cm^{3} } (grams per centimetres cubed).
