What is the molarity for 23.4 g of sodium hydroxide in 250.0 mL?
1 Answer
Explanation:
The molecular weight of sodium hydroxide is
You have
#(23.4cancel("g"))/(39.997cancel("g")/"mol") = "0.585 moles"# .
These
Molarity is moles per liter.
#"molarity" = "moles" / "litre"#
#"molarity" = "0.585 moles" / "0.25 L"#
#"molarity " = " 2.34 M"#
