This has multiple answers can you be more specific
The answer is the second option. The given conversion from L to dm3 is actually confusing. Just remember that 1 L = 1000 cm3.
Simply, multiply 2.6 by 1000 and we get 2600 cm. Converting this to scientific notation, we get the answer:
2.6 x 10^3 cm3
Answer:
m = 25.98 g
Explanation:
Given data:
Density of copper metal = 8.96 g/mL
Volume of copper metal block = 2.90 mL
Mass of copper metal block = ?
Solution:
The volume of given block of copper is equal to the volume change of water by adding this block.
Density formula:
d = m/v
by putting values,
8.96 g/mL = m/ 2.90 mL
m = 8.96 g/mL × 2.90 mL
m = 25.98 g
Answer: At some point in your chemistry education, you may have been introduced to the song “The Elements in which Tom Lehrer does a rapid
fire musical rendition of all the elements' names. Like me, you may even have been offered the opportunity to memorize this song for extra credit. If so, it’s possible that you still remember the names of all the elements, which is an impressive feat—not to mention a fun trick to pull out at parties.
