Powder
Flour
noun
The kanji and the word are exactly the same. That means they share meanings as well. Can also mean flour.
Since this word is made up of a single kanji, it probably uses the kun'yomi reading. You did not learn this reading, so here's a mnemonic to help you to remember:
Just imagine there’s powder all over Conan’s (こな) hands and face. Detective Conan, that is. Conan has been investigating some kind of bakery murder. He had to dig through sacks of flour to find the hidden murder weapon (rolling pin, naturally) and now Conan is just covered in the white, starchy powder.
